The robust switch.
The NW series includes three robust cam switches classified by switching capacity. A solid spherical knob, shaped to fit the square metal shaft with a bank of milled cam disks, controls the positive opening switching contacts embedded in the double contact elements.
Furthermore, generously dimensioned ceramic spark chambers with deionization plates fitted, strong blow-out magnets and a large contact opening distance ensure reliable switching. Optionally, metal fittings for attaching padlocks or a robust housing made of cast aluminum or metal are available.
The NW series has been proven over decades in extreme environmental conditions in cement works, on belt drives, as travel limit switches in the crane sector, simply wherever a robust, durable switch is required.
